No need to resort to calling people "not bright". Hard to say that about somebody who is working on their Master's degree from the Hebrew University in Jerusalem right now. And who works as an archaeologist.
You don't need an archaeologist to "find" examples of mismatch between the Biblical account and facts on the ground.
Jericho is a famous example.
The city was destroyed before the Israelites showed up.
That is just one example. There are other well-known difficulties with the Biblical text. How many people left Egypt in the Exodus? The Bible says 600,000 men of fighting age. This implies a total population of several millions. That is a huge number of people for that period. We can estimate how many people lived in Canaan at the time, from the ruins. The oountry simily could not support so many people.
There are things that archaeology has proven. My favorite example is that of the
altar on Mount Ebal, tough there is controversy regarding that as well.
The Bible in inconsistent. Who killed Goliath?- depends what chapter you read. Where did David take Goliaths head after the battle? Jerusalem- but it hadn't been conquered yet.` How did Saul first meet David? David the warrior who played the harp for him, or David the shepherd with no battle experience who went on to defeat Goliath?
Read the Bible. Pay attention to the details. You will learn something.
